Decompose<T, R1, R2>(T, ValueFunc<T, R1>, ValueFunc<T, R2>)

Performs decomposition of object into tuple.

Declaration

    where T : class

Parameters

Type	Name	Description
T	obj	An object to decompose.
ValueFunc<T, R1>	decomposer1	First decomposition function.
ValueFunc<T, R2>	decomposer2	Second decomposition function.

Returns

Type	Description
ValueTuple<R1, R2>	Decomposition result.

Type Parameters

Name	Description

R2	Type of the second decomposition result.

Decompose<T, R1, R2>(T, ValueFunc<T, R1>, ValueFunc<T, R2>, out R1, out R2)

Performs decomposition of object into two values.

Declaration

public static void Decompose<T, R1, R2>(this T obj, in ValueFunc<T, R1> decomposer1, in ValueFunc<T, R2> decomposer2, out R1 result1, out R2 result2)

    where T : class

Parameters

Type	Name	Description
T	obj	An object to decompose.
ValueFunc<T, R1>	decomposer1	First decomposition function.
ValueFunc<T, R2>	decomposer2	Second decomposition function.
R1	result1	First decomposition result.
R2	result2	Second decomposition result.

Type Parameters

Name	Description
T	Type of object to decompose.
R1	Type of the first decomposition result.
R2	Type of the second decomposition result.

GetUserData<T>(T)

Provides ad-hoc approach to associate some data with the object without modification of it.

Declaration

public static UserDataStorage GetUserData<T>(this T obj)

    where T : class

Parameters

Type	Name	Description
T	obj	Target object.

Returns

Type	Description
UserDataStorage	User data storage.

Type Parameters

Name	Description
T

Remarks

This method allows to associate arbitrary user data with any object. User data storage is not a part of object type declaration. Modification of user data doesn't cause modification of internal state of the object. The storage is associated with the object reference. Any user data are transient and can't be passed across process boundaries (i.e. serialization is not supported)

IsOneOf<T>(T, T[])

Checks whether the specified object is equal to one of the specified objects.

Declaration

public static bool IsOneOf<T>(this T value, params T[] values)

    where T : class

Parameters

Type	Name	Description
T	value	The object to compare with other.
T[]	values	Candidate objects.

Returns

Type	Description
Boolean	true, if value is equal to one of values.

Type Parameters

Name	Description
T	The type of object to compare.

Remarks

This method uses to check equality between two objects.

IsOneOf<T>(T, IEnumerable<T>)

Checks whether the specified object is equal to one of the specified objects.

Declaration

public static bool IsOneOf<T>(this T value, IEnumerable<T> values)

    where T : class

Parameters

Type	Name	Description
T	value	The object to compare with other.
IEnumerable<T>	values	Candidate objects.

Returns

Type	Description
Boolean	true, if value is equal to one of values.

Type Parameters

Name	Description
T	The type of object to compare.

Remarks

This method uses to check equality between two objects.
